The cambrian explosion and fossil records (541 – 245 million years ago) the cambrian explosion was the largest diversification of life in earth’s history. We couldn’t identify life because we didn’t have fossilized shells or animals. This is when hard-shelled invertebrates originated in the oceans.
The sequence of sediments deposited in lakes forms an archive of a high-resolution record of the changes and rates of changes in continental palaeoenvironments. Global geological record of lake basins is the first in a short series of books containing concise geological summaries of lake basin.

4 measuring geological structures geologists take great pains to measure and record geological structures because they are critically important to understanding the geological history of a region. One of the key features to measure is the orientation, or attitude, of bedding. We know that sedimentary beds are deposited in horizontal layers.

An ice age is a period of colder-than-usual global temperatures and bigger-than-usual glaciers and ice sheets.
Geologic evolution through time can be studied through the changes between different layers. It was the work of geologists that began changing the public’s opinion of the grand canyon region from that of “a worthless locale” to “the most sublime of earthly spectacles.
The geologic record of the proterozoic is more complete than that for the preceding archean. In contrast to the deep-water deposits of the archean, the proterozoic features many strata that were laid down in extensive shallow epicontinental seas; furthermore, many of these rocks are less metamorphosed than archean-age ones, and plenty are unaltered.
3 jul 2014 our data also suggest an alternative origin for carbonate nano-sized spheres found throughout the geological record.
Around 435,000,000 years ago, the first land plants evolved, followed by great swamp trees, amphibians, and primitive reptiles. The dinosaurs came on the scene during the triassic period (about 225,000,000 years ago), and by about 180,000,000 years ago, the jurassic period saw the first birds and mammals.
The geologic record in stratigraphy, paleontology and other natural sciences refers to the entirety of the layers of rock strata. That is, deposits laid down by volcanism or by deposition of sediment derived from weathering detritus. This includes all its fossil content and the information it yields about the history of the earth: its past climate, geography, geology and the evolution of life on its surface. According to the law of superposition, sedimentary and volcanic rock layers are deposite.

The fossil forms that occur in the rocks, however, provide the chief means of establishing a geologic time scale, with the timing of the emergence and disappearance of widespread species from the fossil record being used to delineate the beginnings and endings of ages, epochs, periods, and other intervals.
The geologic time scale (gts) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other earth scientists to describe the timing and relationships of events in geologic history.

Drilled through the ice sheets yield a record of polar temperatures and atmospheric composition ranging back to 120,000 years in greenland and 800,000 years in antarctica. Oceanic sediments preserve a record reaching back tens of millions of years, and older sedimentary rocks extend the record to hundreds of millions of years.
